Abstract
In a method for integrating one or more supplementary-function modules in telecommunication exchanges, particularly digital telephone branch exchanges, in which the switching between two subscriber terminals is done in accordance with the time-division multiplex principle by allocation of a pair of time slots by a central switching unit, at least one particular permanently reserved time slot is accessed for communication between the supplementary-function module or modules and the subscriber terminals.
